ABSTRACT

DEVICE FOR CONTROLLING THE OPERATION OF A WINDING UNIT IN AUTOMATIC WINDING MACHINES, SAID WINDING UNIT HAVING A CLUTCH AND A BRAKE. THE DEVICE CONTROLS THE OPERATION OF BOTH THE CLUTCH AND THE BRAKE OF THE WINDING UNIT DURING WINDING, AS WELL AS DURING THE AUTOMATIC REMOVAL OF YARN BREAKAGE, DURING KNOTTING OF THE YARN END FROM A NEW SUPPLY COP, AND UPON ELIMINATING PATTERN WINDING ON THE WOUND BOBBIN. THE DEVICE HAS A SERIES OF CAMS AND LEVERS; A FIRST LEVER FORMS ON ONE HAND A COMPONENT OF MECHANISM FOR DISENGAGING THE WINDING UNIT FROM THE DRIVE, AND ON THE OTHER HAND A COMPONENT OF MECHANISM FOR CONTROLLING THE CLUTCH AND THE BRAKE OF THE WINDING UNIT UPON AUTOMATIC REMOVAL OF YARN BREAKAGE OR UPON KNOTTING THE YARN END OF A NEW SUPPLY COP, SAID FIRST LEVER CONSTITUTING AT THE SAME TIME THE MAIN CONTROL ELEMENT FOR ENGAGING AND DISENGAGING A SINGLE-REVOLUTION CLUTCH THROUGH WHICH THE BOBBIN DRIVING DISTRIBUTOR OF THE WINDING UNIT IS DRIVEN.
